Section 6 Target Tracking and AIS
6-26
6.5.7 Setting target for which ground is fixed to a
reference target
By tracking the target for which ground is fixed and setting it to a reference target, the speed of the own
ship can be obtained and displayed.
The reference target function is to be used if the own ship's speed cannot be
displayed normally due to trouble such as a speed sensor malfunction. Do not use
the reference target function except in emergencies.
Do not set as a reference target a large radar echo such as a land target. The vectors
of the speed and other tracking targets will not be displayed correctly and may cause
an accident.
Do not set as a reference target a sailing ship. The vectors of the speed and other
tracking targets will not be displayed correctly and may cause an accident.
Do not use own speed based on reference target tracking for relative speed and
CPA/TCPA calculation of AIS targets because the response of own speed is slower
than actual own ship's speed change and it may cause a big error on the collision
judgement of AIS targets.
1
Acquire the ground-fixed target.
2
Click the right button on the acquired target.
A context menu is displayed.
3
Click on [Property] in the context menu.
The [TT Target INFO] dialogue is opened.
4
To set the target to a reference target, check [Reference Target].
To not set the target to a reference target, uncheck [Reference Target].
5
Select [TGT] from the COG/SOG source combo box in the own ship information at the
top right corner of the screen.
The ship speed is automatically calculated from the reference target and is displayed as the
COG/SOG speed.
When a reference target is set, the symbol display changes to “
R
”.
